Lawn stripers

I am looking into big league lawns 20' checkmate lawn striper and I am wondering if anyone has used them can they give me some info like how they hold up with everyday use. How many seasons do they last etc etc... Any info would help.

I had them installed on a 36' Wright Stander, I still didn't get the stripes I was looking for. Maybe on a different mower they make work better than the results I got. I ended up selling the mower because of the cut quality.

Is that a 21' mower used in the picture? The lines look wider, but it does look very nice. I am thinking this will be a nice way to get a new business attention but I will be using a 21 inch honda to start out with
